Rickcin - generally, lilacs do not do well in the south. There may be some tolerant varieties but personally I prefer native plants. Did you buy them at a big box or a nursery? Nurseries usually stock plants appropriate to the region; big box caveat emptor. You may try thinning out the shrubs making sure to dispose of the waste, dispose of all the waste / stuff around the base, and not fertilizing the plant for awhile. Dispose means burn or put in the garbage or however your area disposes of trash. Do not put it in a compost pile. The reason not to fertilize is that the fungus may favor newer growth so limiting that condition may be helpful.

To be clear, I buy stuff at big box stores like Lowes and Home Depot, however I know exactly what I want. A nursery usually has knowledgeable staff ready to talk with you. Other possible sources of information include state extension service, botanical gardens, and master gardeners.
